# Bosch error code E100

### What this one means

The appliance has logged an internal electronics error. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.

### What the code covers

A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:

- The control electronics

### What to try yourself

- Turn the appliance off at the breaker and wait five minutes
- Turn the breaker back on and try one bake cycle

### Then what

Broad by design. What matters is whether it comes back after the power cycle — a code that survives five minutes off is a code that means something.

This code is published for ranges and wall ovens. The [full list of codes](https://boschmiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
